    Spreading perennial herb or shrublet 30–80 cm tall, branches decumbent or procumbent; stems with mixed short white ± retrorse hairs and long coarse ± spreading pale-buff or yellow hairs, often also viscid glandular-pubescent at least on upper internodes.
    Leaves sometimes immature at flowering, subsessile, ovate-elliptic to lanceolate, 1–3.5 × 0.5–1.5 cm, base obtuse or rounded, margin revolute when young, apex acute, mucronulate, surfaces with ± dense long pale-buff coarse spreading or ascending hairs, young leaves often viscid glandular-pubescent; lateral veins 2–4 pairs.
    Inflorescence axillary, 1(2)-flowered, densely viscid glandular-pubescent throughout; peduncles spreading-ascending, 9–26 mm long; bracteoles linear(oblanceolate), 5–13 × 1–1.5 mm, margin entire, apex spinulose; pedicels (1)4–16 mm long.
    Calyx pale green or brownish at first with darker reticulate venation, later turning scarious; outer lobes subequal (posterior lobe marginally longer), elliptic, oblong or lanceolate, 11–19 × 3.5–6 mm, margin entire, apex acute, attenuate or anterior lobe sometimes notched to 2.5 mm, mucronate, surfaces densely glandular-pubescent and sparsely strigose; lateral lobes linear-lanceolate, 9–15 mm long.
    Corolla 45–56 mm long, pale pink to mauve or white, limb sometimes with darker magenta stripes, pubescent externally with mixed eglandular and glandular hairs; tube cylindrical, 26–35 mm long; limb in 2+3 arrangement; abaxial lobe c.18 × 10–15 mm; lateral lobes 17–21 × 10–17 mm; adaxial lobes as laterals but 7–13 mm wide.
    Stamens attached 15–18 mm from base of corolla tube; filaments 21–25 mm long; anthers 3–5 mm long; lateral staminodes 2.5–6 mm long, sparsely hairy at base, apex clavate, antherodes undeveloped.
    Ovary with tuft of deflexed hairs at apex, proximal portion of style often with scattered longer hairs; stigma subcapitate or clavate, 0.3–0.5 mm long.
    Capsule 18–19 mm long, glabrous.
    Seeds not seen.
    Also in southern D.R. Congo.
    Dry rocky or sandy hillslopes with open vegetation or stunted Brachystegia woodland; 1000–1250 m.
    Conservation notes: Very localised and scarce, known from only 10 collections, mostly in the vicinity of the Great East Road in SE Zambia; no information available for the Congo population; probably Vulnerable under IUCN criterion B.
